Answer:
-7
Step-by-step explanation:
Step 1: Make an equation.
- [tex]9 + x = 2[/tex]
Step 2: Subtract 9 from both sides.
- [tex]9 + x - 9 = 2 - 9[/tex]
- [tex]x = -7[/tex]
Step 3: Check if solution is correct.
- [tex]9 + (-7) = 2[/tex]
- [tex]9 - 7 = 2[/tex]
- [tex]2 = 2[/tex]
Therefore, the integer that makes the addition sentence true is -7.
